  1. 1. Time Series databaser för sensorsystem : En experimentell studie av prestanda för Time Series databaser för sensorsystem som grundas på: NoSQL eller RDBMS.

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Datateknik och informatik

    Författare :Linus Warrén; Daniel Tallkvist; [2019]
    Nyckelord :Time Series DBMS; NoSQL; RDBMS; TimescaleDB; InfluxDB; Sensor systems; Time Series DBMS; NoSQL; RDBMS; TimescaleDB; InfluxDB; Sensorsystem;

    Sammanfattning : Purpose – The purpose of this study is to recommend a database and its belonging database model which is optimized for a sensor system. There is a lack of comparisons for databases and data models for bigger sensor systems. LÄS MER

  3. 2. Object Migration in a Distributed, Heterogeneous SQL Database Network

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Joakim Ericsson; [2018]
    Nyckelord :Database; DBMS; Distributed Network; Heterogeneous; SQL Database; RDBMS; relational; Performance;

    Sammanfattning : There are many different database management systems (DBMSs) on the market today. They all have different strengths and weaknesses. What if all of these different DBMSs could be used together in a heterogeneous network? The purpose of this thesis is to explore ways of connecting the many different DBMSs together. LÄS MER

  4. 3. Investigating the scaleability of analyzing and processing RDBMS datasets with Apache Spark

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Nyckelord :;

    Sammanfattning : At the Uppsala Monitoring Centre (UMC), individual case safety reports (ICSRs) are managed, analyzed and processed for publishing statistics of adverse drug reactions. On top of the UMC’s ICSR database there is a data processing tool used to analyze the data. LÄS MER

  5. 4. Large Scale ETL Design, Optimization and Implementation Based On Spark and AWS Platform

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Di Zhu; [2017]

  7. 5. Scalability study of database-backed file systems for High Throughput Computing

    Kandidat-uppsats, Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Författare :Andy Trinh; [2017]
    Nyckelord :database-backed file system; dbfs; scalability; xfs; ext4; database; file system; fuse; arc; read performance; alternative storage; rdbms; file system interface; Technology and Engineering;

    Sammanfattning : The purpose of this project is to study the read performance of transparent database-backed file systems, a meld between two technologies with seemingly similar purposes, in relation to conventional file systems. Systems such as the ARC middleware relies on reading several millions of files every day, and as the number of files increases, the performance suffers. LÄS MER
